ADSP-21160NCBZ-100

Digital Signal Processor Dsp Overview

The ADSP-21160NCBZ-100 is a high-performance 32-bit floating-point digital signal processor from the Analog Devices SHARC family. Fabricated using a 0.18 micron CMOS process, it operates at a core instruction rate of 100 MHz with a 10 ns cycle time. The device features a Super Harvard architecture with four independent buses, enabling dual data fetch and instruction fetch in a single cycle. It includes two computational processing elements (PEX and PEY) supporting Single-Instruction Multiple-Data (SIMD) operations, providing up to 200 million fixed-point MACs sustained performance. The processor integrates 4 Mbits of on-chip dual-ported SRAM, an I/O processor, and multiple interfaces including serial ports, link ports, and a host port.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix 'CBZ' against the manufacturer's current ordering guide to confirm package type and lead-free status. Ensure compatibility with existing system power supplies, as the ADSP-21160N requires a 1.9 V core voltage and 3.3 V I/O voltage. Confirm that the 400-ball PBGA package dimensions fit the target PCB layout constraints.

Digital Signal Processor Dsp Selection Notes

Select the ADSP-21160N variant over the ADSP-21160M when higher performance (100 MHz vs. 80 MHz) and lower power consumption are required. The ADSP-21160N utilizes a 0.18 micron process compared to the 0.25 micron process of the M variant. Ensure software development tools support the SIMD architecture if dual-channel processing is intended, as code changes may be needed compared to SISD-only applications.

Digital Signal Processor Dsp Part Context

The ADSP-21160x family consists of the ADSP-21160M and ADSP-21160N. The N variant offers superior performance due to its advanced 0.18 micron CMOS fabrication technology. This component is backward compatible at the assembly source level with first-generation ADSP-2106x SHARC DSPs in SISD mode, facilitating migration from older platforms while gaining SIMD capabilities.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21160M is a direct functional alternative within the same family but operates at 80 MHz. For pin-compatible replacements, verify the specific package suffix; however, different suffixes may indicate variations in temperature range or packaging material rather than electrical function.
